Central to the platform is the promise "to build a cleaner, more sustainable, more affordable and more caring WA" with the commitment to run a positive campaign.

Greens Leader and Member for the North Metropolitan Region, Giz Watson said the Greens believed that voters were tired of political parties slinging mud at one another and resorting to personal attack and the Greens would campaign on issues rather than personalities.

"We will play the ball not the candidate," Ms Watson promised.

The Party, which currently only holds four seats in Western Australia's Legislative Council, or Upper House, has focused its campaign on eight key policy areas – transport, renewable energy, housing affordability, education, water, environment, mental health and employment.

Ms Watson said among other things, the True Progress platform meant looking after the needs of the community and sharing the benefits of the mining boom more fairly.

"Many West Australians are really struggling with spiralling living costs, particularly housing and utilities. We are campaigning for true progress that seeks to improve the living standards of all West Australians now and into the future," Ms Watson said.

She said the platform also aims to build reliable public transport networks, make housing more affordable and increase investment in renewable energy.

The Party also confirmed it be running candidates in every seat in both Houses and promised to use social media "in ways not previously seen before in WA to reach out to voters in the digital environment," Ms Watson said.
